Pressure reducing valves (PRVs) are specialized flow control devices designed to reduce high inlet pressure to a stable, preset lower outlet pressure. They automatically maintain the desired outlet pressure regardless of fluctuations in inlet pressure or flow rate. Composed of valve body, pressure-adjusting mechanism, diaphragm and sealing components, they protect downstream equipment and ensure system safety and efficiency.
Robust and compact structure, with a precision pressure-adjusting mechanism for accurate pressure control. The valve body is made of corrosion-resistant materials (stainless steel, brass, carbon steel), adapting to high-pressure, high-temperature and corrosive fluid environments. The diaphragm-driven design ensures sensitive and stable pressure response.
Automatic pressure regulation, maintaining stable outlet pressure even with inlet pressure or flow fluctuations. High pressure-reducing accuracy and good sealing performance to prevent fluid leakage. Overpressure protection function, avoiding damage to downstream pipelines and equipment, and easy pressure adjustment for different application needs.
Simple structure, relying on spring and diaphragm force for pressure regulation. Suitable for small flow, low-to-medium pressure systems such as residential water supply, HVAC and light industrial equipment.
Equipped with a pilot valve for precise pressure control, suitable for large flow, high-pressure industrial systems. Widely used in petrochemical, power generation, chemical processing and water treatment industries.
Widely applied in industrial and civil fields, including petrochemical, power generation, chemical processing, water supply and drainage, HVAC, residential and commercial buildings. They are essential for reducing high mains pressure to safe levels, protecting pumps, meters, valves and other downstream equipment.
